光学相干断层扫描在高度近视黄斑裂孔硅油填充术后的疗效评估

Efficacy assessment of optical coherence tomography in high myopia macular hole after silicone oil tamponade

目的: 光学相干断层扫描(optical coherence tomography,OCT)评价高度近视黄斑裂孔硅油填充术后疗效评估。方法: 回顾性分析20例20眼高度近视黄斑裂孔伴视网膜脱离行玻璃体切除术后硅油填充的病例,术后平均随访7mo,随访时给予OCT检查,评估黄斑裂孔闭合及视网膜复位,记录最佳矫正视力情况。结果: 术后OCT表现有3种:黄斑裂孔闭合2眼(10%),黄斑裂孔未闭合但视网膜复位16眼(80%),黄斑裂孔未闭合伴视网膜浅脱离2眼(10%)。术后最佳矫正视力较术前有所提高,视力的提高与黄斑孔的解剖学复位情况密切相关。术后无严重并发症发生。结论: OCT用于高度近视黄斑裂孔硅油填充术后随访可以明确诊断黄斑裂孔闭合及视网膜复位情况,为硅油取出时机提供参考。

·AIM： To evaluate the efficacy of optical coherence tomography （OCT） in highly myopic macular hole after silicone oil tamponade.·METHODS： A retrospective analysis of 20 cases of high myopia macular hole with retinal detachment after vitrectomy with silicone oil tamponade was performed. The mean follow- up time was 7 months. OCT examination was given to assess the macular hole closure and retinal reset during the follow-up. Best corrected visual acuity （BCVA） was recorded.· RESULTS： There were three kinds of postoperative OCT performance： macular hole closure in 2 eyes （10%）, macular hole was not closed but the retinal reattachment in 16 eyes （80%）, macular hole was not closed with shallow retinal detachment in 2 eyes （10%）. Postoperative BCVA improved compared with that of preoperative. The improvement of visual acuity was closely related to the anatomy reset of macular hole. No serious postoperative complications occurred. ·CONCLUSION： OCT for macular hole in high myopia silicone oil tamponade postoperative follow- up can confirm the diagnosis of macular hole closure and retinalreset, providing the means of reference for the timing of silicone oil removal.
